    Summary
    This summary is machine-generated.

    Necrotizing duodenitis in foals causes full-thickness wall damage and peritonitis. Chronic forms lead to strictures and organ damage, with no specific infectious agent identified.

    Area of Science:

    • Veterinary Pathology
    • Equine Medicine
    • Gastroenterology

    Background:

    • Necrotizing duodenitis is a severe gastrointestinal disease affecting foals.
    • The condition can lead to life-threatening complications such as perforation and peritonitis.

    Purpose of the Study:

    • To describe the pathological findings in foals with necrotizing duodenitis.
    • To investigate potential etiological agents and contributing factors.

    Main Methods:

    • Histopathological examination of duodenal and gastric tissues from affected foals.
    • Microbiological culturing (aerobic and anaerobic).
    • Electron microscopy for viral detection.
    • Immunofluorescence staining for specific equine viruses.

    Main Results:

    • Acute necrotizing duodenitis with full-circumference segments or bands, leading to perforation and acute fibrinous peritonitis in seven foals.
    • Chronic duodenitis characterized by thickened walls, granulation tissue, strictures, adhesions, cholangiohepatitis, and pancreatitis in two foals.
    • Gastric ulcers were present in eight foals but considered secondary to duodenal lesions.

    Conclusions:

    • Necrotizing duodenitis in foals is a severe condition with acute and chronic presentations.
    • No infectious etiology was identified, suggesting other factors like non-steroidal anti-inflammatory drugs may be involved.
    • The disease can result in significant gastrointestinal and associated organ pathology.
